The product range of electrochemical sensors was exceeded with H2O2-Sensors, e.g. to monitor sterilization processes with Hydrogen Peroxide, and with ETO-Sensors for the measurement of Ethylene Oxide in the lower ppm-range. Hence, there are now selective sensors available for 18 different gases.
For Biogas-Applications special H2S-Sensors were developed, which exhibit a significant higher resistance against poisoning also at high concentrations.
For the Flue Gas Sensors the filter capacity could be increased by 20%.
